Why do battery's get hot...?

Question

I picked up my tv controler and the batterys were burning through, they were realy hot. Why?

Answer 1

You have a faulty battery and better change it as soon as possible as faulty battery can be harm full to you and so as your electronic product.

Answer 2

Batteries don't get hot unless they're defective or have had a lot of current used out of them.  If your remote works, you have to assume it wasn't drawing excessive current.  This pretty much leaves a defective battery.  As the other answer says, you should replace it as soon as possible.  At least remove it from the remote to prevent damage to the remote.

Answer 3

Maybe you left on something hot or kept doing something with it too long.
